SIP <-> SS7 GatewaysSS7 (or C7) is the main signalling for PSTN interconnections. How do we interface between a SS7 network and a SIP network?
- Introduction to SS7 Signaling - This free tutorial provides an overview of Signaling System No. 7 network architecture and protocols.
- SIP to SS7 Gateway from Terratel The signaling converter allows to combine systems that use different signaling protocols (SS7, PRI EDSS1, V5.2, V5.1, R2D, CAS, SIP) into a unified telecommunications network. Effective integration TDM to NGN and IMS networks.
- SIP Network to SS7 Interconnection This scalable solution provides interworking between SIP and SS7 at one or multiple points of presence.
